MOP.

. SPECIFICATION forming part of Letters Patent No. 868,486, dated August16, 1887.

Application filed Dccembr r 16, 1885. Serial No. 185,951. (No model) Toall whom it may concern.-

Be it known that I, Josnrr-r H. One, a citizen of the United States,residing at Toledo, in the county of Lucas and State of Ohio,

have inventeda new and useful Improvement in Mops, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

This invention relates to mops; and it consists in the peculiarconstruction and combination of parts, as will be hereinafter fully setforth and claimed.

In the accompanying drawings, Figure 1 is a perspective view ot'myimproved mop,showing the parts in the position assumed when adjustingthe cloth. Fig. 2 is a longitudinal section taken centrally through Fig.3. Fig. 3 is a plan view showing theparts adjusted in position for use.Fig. 4 is a side elevation, with the clamping-wire partly broken away.

Like letters are used to indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates the handle of the mop, to oneend of which is fitted the short tube or ferrule B of the rigidjaw O.The tube B projects laterally from one side of the jaw O at or about themiddle thereof, being formed integral with thejaw, and having its frontor outer end partially closed around the extremity of the handle, asshown in Fig. 2. The jaw O has its outer face concaved, to provide alongitudinal groove, D, the ends of the jaw being rounded or curved, asat a, the groove D also extending through the rounded ends, as will beseen.

E designates the movable clamping-jaw, made of a single piece of heavywire and comprising the main clamping-arm Z), arranged parallel with therigid jaw O, the side arms, (1 (Z, connect-ing with the main arm I) atthe rounded ends a of the rigid jaw and bent inwardly from the point e,and the angular bends f at the extremities of the side arms, thelatterbeing turned or bent inwardly toward the 5 handle from the point c,tosuch a degree as to cause the bendsfto come within an eighth of an inchorso of the handle. The bendsf may either be provided with enlargedheads on the ends, or, as shown in the drawings, the ends may be turnedback or to one side, as at g, for the purpose presently described.\Vear-plates F are secured by screws or rivets to opposite sides of thehandle A,and are perforated at h to register with corresponding openingsif in the handle.

G designates the clamping-lever, constructed of a single piece of heavywire in the form of a U, the endsj of which are inserted through theperforations h i of the wear-plates F and handle A, so as to journal orpivot the lever in place. The side arms of the U-shaped lever G are bentto form eyes k below the plane of the arms, and in these eyes the bendsfof the clamping-jaw E are received. The enlarged or turned-back ends gof the bends f prevent the clampingjaw E from separating from the leverG. The middle or doubled portion of the U -shaped lever G is extendedabove the plane of the side arms, so as to fit over the top of thehandle.

The operation of my invention is as follows: To insert the cloth or ragwhich forms the mop proper, the lever G is thrown forward by catchinghold of its central doubled portion, the lever having its journals orends working in the handle, and by the forward movement pushing theclamping-jaw E outward beyond the rigid jaw O, as shown in Fig. 1. Thecloth is then adjusted in position between the two jaws O E and thelever G operated in a reverse direction or thrown backward until itscentral doubled portion strikes the handle, the clamping-jaw E beingdrawn back to bind the cloth or rag in position.

It will be seen that the side arms, d, of the clamping-jaw E areretained at all times within the grooved ends a of the rigid jaw O,sothat when working the clamping-jaw forward or backward it will be guidedin its movements, and will also be held from springing laterally. Thewire-clamping jaw E, being smaller in diameter than the groove D of therigid jaw, will serve to bind the cloth or mop within the groove andprevent its detachment when the mop is in use.

The peculiar inward bend of the side arms, d, of the clamping-jaw Eimparts a spring thereto,so that the main arm b will adjust itself toany thickness of the cloth or mop. In

operation, the main arm I) draws upon the side arms, (I, and tends tostraighten the latter horizontally by reason of the inward bend given tothe side arms.

Should the clamping-j aw E become sprung by constant use, or should itbe desired to impart a greater binding action thereto, a series of holesmay be provided along the plate F,to

receive the journals or ends 9' of the clampinglever,and thereby set thepivot-point thereof farther back, the consequence of which would be togive to the clamping-j aw increased power to hold the cloth or mop inplace.

The central doubled portion of the clampinglever G serves as the handletherefor, and by locating the handle end above the plane of the sidearms and the pivot-point and causing it to rest on the mop-handle a camaction is given to the clamping-lever, which will materially assist inholding the parts in their adjusted positions. It will be "observed thatwhen the clamping lever is swung down in position against the handle theresistance which the mop offers serves to force theleverin a greaterdegree against the handle,so that proportionately to the amount oftension applied to the mop the handle G will be forced correspondinglydown upon the mop-handle. ThusI provide against all possibility of thedetachment of the parts.

I am aware that in the patent to Davis,No. 257,294, it was proposed toprovide a mopholder comprising a'rigid jaw and a pivoted lever connectedto the clamping-jaw; but in thispatent the pivot-point of the lever wason the same plane with the free end of the lever,

so that the lattercould not bind down with any force upon the handle,and thus when any strain was brought upon the clampingj aw the lever hada tendency to swing up and release the jaw.

In the patentto Prosser,No. 7 2,67 7 ,the same general features of theDavis mop are shown; but in the former case the free end of the clampinglever was above the pivot -point thereof, but still the connection ofthe clamping-jaw with the lever was on the same line. In my mop I go astep farther by making the free end of the lever Work down upon thehandle above the pivot-point of the lever, and also above the pointwhere the clamping-jaw is connected, so that the strain on theclampingjaw is brought directly on a line with the pivot of the leverand not against the free end of the lever. In this manner all thetendency of the clamping-lever to work up and release the parts isentirely overcome.

Having thus described my invention, I claim- The combination, with thehandle and rigid jaw, of the keeper consisting of the clampingjtw andthe elastic limbs, and-the U-shaped clamping-lever having its endspivoted to the sides of the handle and its central portion crossing thehandle and resting upon it when the clamping-jaw is locked, the sides ofsaid clamping-lever being provided with eyes to which the ends of thekeeper are loosely connected, whereby the keeper may be loosened for theinsertion and removal of the mop-cloth and tightened to clamp saidcloth.

In testimony, that I claim the foregoing as my own I have hereto affixedmy signature in presence of twowitnesses.
